Model of thermal plume above cooking gas stove for designing ventilation

A model of the thermal plume above a cooking gas stove using computational fluid dynamics (CFD) analysis was studied to predict the heat and vapor released during cooking. The combustion gas released from the burner installed in the gas stove was considered as air in which thermal energy was adjusted so that the thermal plume above the gas stove could be simulated. Therefore, the model could predict the thermal plume above the gas stove based on the capacity of the burner and pot size. For validating the simulated flow fields, the results of the velocity distributions above the gas stove calculated using CFD analysis models were compared with the results of the velocity distributions measured with particle image velocimetry (PIV). In conclusion, the analysis results were in good agreement with the measurement results. However, the velocity in the vertical direction calculated using CFD above the center of the burner was higher than the velocity measured using PIV along the axis from the center of the burner.
